Dieters who join support groups experience less stress than dieters who try to lose weight on their own, according to nutrition scientists from the U.S. Agriculture Research Service. In an eight-week weight-loss study of healthy, overweight women, ages 23-45, those who attended a weekly support group had lower levels of stress and better memory capacity than their counterparts in the non-support diet group. Researchers surmise that the stress of dieting may cause some people to quit their weight-loss programs too soon.

Conclusion: If the thought of dieting stresses you out, consider joining a weight-loss support group.
